Comparison Study of Effective Length Method (ELM) and Direct Analysis Method (DAM) for Piperack

Authors(2) :-Sabade Madhuri, Prof. A.A.Hamane

Pipe racks are structures in petrochemical, chemical and power plants that are designed to support pipes, power cables and instrument cable trays. AISC 360-05 recognize effective length method and direct analysis method for stability analysis. In this thesis a study has been conducted on the pipe rack structure to compare these methods using the 3D structural analysis program STAAD.Pro V8i considering general requirements such as influence of second order effects (P-Δ and P-δ effects), flexural, shear and axial deformations, geometric imperfections and member stiffness reduction due to residual stresses. In this thesis, a study has been conducted on piperack structure to compare Direct Analysis Method and Effective Length Method. At the end, conclusions are drawn about the comparison of these two stability methods.
